White House: Policy 'czars' won't testify - Washington Times

"he debate goes to the heart of weighty constitutional issues about separation of powers. The president argues that he should be allowed to have advisers who are free to give him confidential advice without having to fear being called to testify about it. Democrats and Republicans in Congress, though, argue that those in office who actually craft policy should be able to be summoned to testify because they do more than just give the president advice.

At issue are the 18 positions Miss Collins says Mr. Obama has created since he took office. Of those, she says 10 - the White House says eight - are in the executive office and not subject to Freedom of Information Act requests or requests for testimony."
